SOLE-IROUNDING- MACHINE.

Application filed October 29, Serial 1,, Specification of Letter"Patent.

To all whom it may concern:

Be it known that l, llILLn-Jr Karon LEY, a citizen of the United States,residing in Vineland, New Jersey, have invented certain improvements inSole-Rounding Machines, of which the following is a specification.

My invention relates to that class of in; chines particularly designedfor shaping or rounding a sole after it has been applied to a weltedshoe; one object being to provide a machine whereby it shall be possibleto more rapidly trim or round the sole of a shoe than has hitherto beenpossible with machines formerly used for this purpose; it being alsodesired that the machine shall be capable of making a clean cut and.producing a finished article of a high grade. 1' also desire to providea sole rounding machine having the above characteristics in which novelmeans shall be provided for feeding the work to the knife and regulatingthe cut thereof, as well as for indenting the welt when this shall be cesirable. Taese objects and otheradvantageous ends it cure ashereinafter noted, reference being had to the accompanying drawings, in

' which Fi ure l, is a side elevation partly in sec tion illustrating myinvention; Fig. 2, is a front elevation of the device shown in Fig. l,and Fig. 3, is a side elevation, to some extent diagrammatic and partlyin section, showing another form of rotary feeding and regulatingdevice.

In the above drawings, 1 represents an endless band knife mounted in anysuitable manner, usually upon pulley Wheels (not shown) which may bedriven in the Way well known in the art. In the present instance thismachine is provided with a work supporting post Qso placed as to projectimmediately adjacent to the front run of the band knife. A suitablemember projects from the frame of themachine above the post 2 and servesto support two plates 3 and 4. immediately adjacent to and on oppositesides of the upper portions of the band knife so to constitute rear andfront guards whose lower ends extend to within a short distance of thetop of said post 2. This post has hearings in its upper portion for thereception of a shaft 5 driven from any suitable sourceof power andextendin rearwardlyfroro the band knife. a conical too-shed feed wheel 6Whose base It carries 1 the rear face 0 thereof is made at thimmediately to r i" said l-Z l'l sired it may be short it the cuttingedge of the 5 and is is such that iof the knife Y work support which, inthe shown in Figs. 1 and consists ot a co gated or toothed wheel 9 whichis prei'icrahly of a conical form and c rried n in a bracket 8detachabiy monnted upon the plate 7. 7c While this wheel maybe at"ichedto any source of powen I preferably rive it at the same speed as thatof" the wheel (3 by means of a worm l0, worni wh ll, shaft L. and wormwheel 13 which engages directly with this wheel; the woru'i 10 being;driven from any suitable source of power.

Under operating conditioina shoe whose its cons nd i sole 1 is to betrimmed or roll ed is presented to the machine in the pa. ion shown inFigs. 1 and 3. the cut starting- .t the heelv portion and eat idin g arot ie shank, ball, toe and back to the heel )und which it may also passit tlQ-Sil't The front guard disthus interposed bet on the upper 8 ofthe shoe and the knife, so th regulates the amountto be trimmed oh ol'the sole or the depth of the out. The todhed feed roll 8 is rotatedthrough the nd serves to feed th sole to he trinnncd at. a prede- 96termined rate past the knife. such case the shoe to be trin'une'd is fedpast the band knife by the combined action ot the two teed wheels 6and't which, as shown. in Fig. 1, are mounted with their basesrespectively adjacent to, orvis shown in l i if, immedi ately in frontoftheband knii In order to properlyregulate the cut, may, as shown in lci3 i'nount on the lower end of the front guard a a conical rotary 0 Wheel15 driven positively or not as desired and Wl1lf3l1,l1l6 a wheel 10 (l ii} will hold the body of the shoe at the p oper distance away from theband knife so t the out o proper 5. 5% of the G5 sole. It said wheel 15was power 11 rivem it would serve both. as cuard and also as a feedwheel in that Ill ot the tfievicc 3, the two whee and t)- acl. to mo 5strongly press to nther thev welt and sole or a shoe operated on and ifeither or both wheels are toothed, the device may act as an indentingmachine. The machine thus performs the functions of a sole rounder, a.welt and sole COIIIPIQSSOIgtlQd an indentor. In this case the wheel 15is positively turned by power from a shaft 17 connected to it through auniversal joint 18.

From the above figures, it will be seen that the machine may be operatedwith a rear, front, or top feed, or with any desired combinationthereof; the preferred construction however being one in which one ormore toothed feed wheels are mounted immediately adjacent to the cutter,and to one side of its cutting edge, with a suitable guard or feed wheelspaced away from said first wheel or wheels so that the sole and weltmay ass between them as shown.

1. A sole trimming machine consisting of a bandknife; a gage adjacentsaid knife for limiting the approach of the body of a shoe toward thesame; a feed wheel adjacent said knife; both the gage and the feed wheelabutting on the sameside of the operative run of said knife, and meansfor driving said wheel.

2. A sole trimming maclnne consisting of a band knife; a gage mountedadjacent to said knife; and placed to limit the approach of a shoethereto; and a feeding device, also adj acent tosaid knife, but spacedaway from said gage so as to permitof the introduction of a sole to betrimmed between itself and the gage; both the: feeding device and thegage abutting against. a straight run of said band knife.

3. The combination of a band knife; a work support on one side of theknife; a work feeding device; and a gage for limiting the approach of ashoe to the said knife; there being a straight run of the knifeextending between said gage and one of the two other devices.

4. The combination of a band knife; a work support on one side of thesame, a feeding device on the .other side of the knife; and a gage alsoadjacent to the knife but spaced away from the work support and feedingdevice as permit of the introduction of a sole to be trimmed; the worksupport, the feeding device, and the gage all abutting upon a straightrun of said knife.

' '5. The combination of a band knife, with a rotary work support on onesideof the plane of the knife; a rotary feeding device on the othersideof said plane; said support and feeding device abutting on a straightrun of said knife; and a gage adjacent to the knife; but s aced awayfrom the supporting device and ceding means, to permlt of the tweenthem.

passage of a sole; the operating run of the band knife beingsubstantially at right angles to the axes of rotation of the work planeand having their flat faces immediately adjacent to and parallel withthe knife, said wheels being arranged to compress between them the soleand welt of a shoe and one of the wheels being placed to serve as a gageto maintain the body of a shoe ata predetermined distance from theknife.

8. A sole rounding machine consisting of a band knife; with two rotarywheels mounted adjacent to said knife and arranged to compress betweenthem the sole and welt of a shoe; one of said wheels being placed toserve as a gage to maintain the body of a shoe at a predetermineddistance from the knife and being provided with teeth for indenting thewelt; 7

9. The combination in a sole rounding machine of a band knife; a rotarywheel on one side of the plane of said knife; and two rotary wheels onthe other side of said plane, one of said wheels being spaced apart fromthe others so as to be capable of compressing the sole and welt of ashoe passing be- 10. The combination in a sole rounding machine of aband knife; a rotary wheel on one side of the plane of said knife; andtwo rotary wheels on the other side of said plane; one of said wheelsbeing spaced apart from the others so as to be capable of compressingthe sole and welt of a shoe passing between them; with means for drivmgone or more of said wheels. 7

11. A sole rounding machine consisting of a band knife; with t\ *orotary wheels mounted adjacent to said knife so as to abut upon thestraight run of the same and spaced to compress between them the soleand welt of a shoe; one of said wheels being provided with teeth forindenting the welt.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing'witnesses.
